I have a 7290 and recently upgraded the handheld software to 4.0.2.49.
Everything works fine and fast. The only problem I have (I assume after this upgrade but not sure) is that when I scroll through text messages in the general messages folder (where emails and text messages arrive) the scrolling has a delay from one line to the other. As I move from the first msg to the 10th, let's say, my trackwheel rotates 10 times but the highlighted text msg is the 5th or 6th one.

I have noticed though that this only happens with text messages. If I have 10 email messages the scrolling is perfect. Likewise for phone calls logs and other items.

The other strange thing is that when I try to reply a text message and I start typing, there is also a delay in the appearence of the letters on the screen. In other words if I type "this is a test.." the word "this" will appear after I finished typing the word "test"! ... but then it works fine for the rest of the letters I type.

Also, clicking on the "Message" icon I can notice a delay in opening that application, only if text messages are contained in there. If emails are the only items in there, then no delay at all, even if emails content are quite large as I have tested.

Anyone has experienced this problem?
(History and logs are kept clean and do not have many msgs stored in there. I removed the battery and reset the handheld..did not fix this). I removed IM, and did not fix the problem.
